To all whom it may concern-1: i

Be it known that I, Fanning; A. Re n ERTS, citizen of the United States, residing at Dickey, in the county of Lainoure and State of North Dakota, haye invented certain new and useful Improvements in J our rial-Boxes, of which the following, is a specification. f i i This invention relates to car axle journal boxes and has for its object to provide a novel packing for such a box. Itisa wellknown fact that in the ordinary construe tion of car axle ournal boxes the lubricant is liable to. leak from the box around that portion of the journal which fits through the rear end of the box.

The present invention, therefore, aims to boxot this type, a novel packing so constructed that the es cape of lubricant from the box through the opening in the rear Fall thereof willbe It is, of course, customary to arrange a the journal immediately inwardly ofthe rear wall of the journal box, butthe ordinary forms of washer and gaskets are notlsuited for usein this connection for of their openings soon become worn and the lubricant is allowed to lea-lr ii'roin the box.

It .is therefore, a turtheraim of the invention to provide a washer which will at all times snuglyfit about the journal and, which will, as it becomes worn, contract so as to prevent leakage of the lubricant around the journal.

will also beobserved from inspectionof the said Fig. 1 that the brassb is located within the forward one of the two chambers resulti ing from the PL'OVlSlOTlOTf the partition 11. the usual waste 12 being also 1 arranged within the said forward chamber. M The par tition 11 is formed with an opening 13 which is:in. alineinent with the opening 9 and it will be observed that the journal 10 extends through the opening 13 andinto the said forward chamber. It is within the rear one of the two chambers above mentioned that the packing embodying the present invention is arranged, and this packing will now he specifically described,

The packing above inferred to includes among other elements a washer which as before stated, is designed to snugly fit the journal 10, immediately inwardly of the rear wall 8 of the box and this washer includes in its structure an annular core 14: which is in the nature of an endless spiral spring. A sheath 15 of clothor other suitable material is woven about the core 14 as clearly shown in Fig. 3 of the drawing and constitutes the bearing surface of the washer.

in forming the washer above described,

the annular core 1 L is slightly expanded and the sheath 15 is then applied to the core. The finished washer is interiorly of a diameter less than the portion of the journal about which it is to fit; and in. applying the washer to the journal the washer is exwill, when applied to the journal, snugly fit about the same. In order to accomplish the desired result, namely to prevent leakage of the lubricant, from the box, the washer above described must bear snugly against the, inner face of the rear wall 8 of the box at the opening 9 therein and in order that it may be at all timesheld in this position, a coil springlti is arranged upon the journal 10 and bears at one end against a metallic washer 17 and at its other end against that face of the partition 11 which is presented toward the inner face of the rear Wall 8 I of the box.

Itwill be observed from inspection of Fig.

1 of the drawing that the washer l7 loosely fits the journal 10 and that the point at which it engages against the packing washer is diametrically opposite the point of engagement of the packing washer against the inner face of the rear Wall '8 so that the, spring 16 bearing firmly against'the washer 17, serves to at all times, hold the packing washer snugly and firmly against the rear wall of the box regardless of any endwise thrusts to which the journal 10 may be subjected.

' Having thus described the invention what is claimed as new i The combination with a journal boX and journal, the box having a partition spaced from that Wall through which the journal is projected, of a packing gasket encircling the journal and bearing against'the inner face of that wall of the boX through which the journal is projected, said gasket includa core consisting of an annular helical spring, and a sheaf of packing material covering the core, a washer loosely fitted .on the journal and interposed between the gasket and the partition, a helical spring loosely wound around the journal and bearing at one terminal against the partition wall and at its opposite terminal against the washer for yieldably urging the washer against the gasket, whereby the gasket is yleldably held into engagement with the inner face of that wall of the box through which the ournal is projected, the convolutions of the last- Copies of this patent may be obtained for five cents each, by addressing the "Commissioner of Patents,
